Bridge Tool & Die: CNC Turns ‘Feel’ Into High-Precision Carbide Grinding

Glenn Bridgman describes the difference between his shop’s manual grinders and its newest state-of-the-art CNC ID/OD grinder, a Studer CT960 OD/ID from United Grinding (Miamisburg, OH), as “feel vs. facts.” Bridgman, president of Bridge Tool & Die (Buckley, MI), believes that manual grinding is a somewhat personal operation.

Testing the Metal

Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.

Sorting Out the Options Leads to Successful Presetting

With the number of offline and in-process toolsetting options on the rise, developing a way to efficiently utilize this technology can be confusing. Which presetter should we buy? What about the software that’s so often part of these systems—do we really need it?

Advances in Machining Technology Enable Competitive Advantages for Brass

As a result of recent testing under real production conditions, brass proved to machine at extremely high speeds on today’s advanced machine tools with little evidence of tool wear, producing high-quality surface finishes and excellent chip control, reported the Copper Development Association (McLean, VA).

The Future of Robotics in CNC Grinding

The International Federation of Robotics (IFR) in 2016 showed unit sales figures in 2015 up 15% on the year before, reaching an all-time high of 253,748. Since 2010, technical improvements in robots and automation have turbocharged investment, according to the report.

Metrology, Product Design and the Next Revolution

When I graduated with an engineering degree some decades ago, I learned that the organizations I was going to work for had internal communication problems. This was especially true for those that designed and manufactured complex machinery such as engines, aircraft, or automobiles.

Software, Quality Inspection Deliver Auto Parts Safety

Although drivers may not know it, cable connections for the airbags and seatbelt buckle systems in their vehicle simply would not work without components manufactured by ODW-Elektrik. A development partner and supplier for high-quality cabling, solenoids and mechatronic systems used in vehicles around the world, ODW-Elektrik supplies most of its products to Bosch, Autoliv, Brose, VW, and ZF.
